Description

Method for forming curved surface of decoration board

Conventionally, in various furniture products, when designing curved surfaces, when synthetic resins, metals, etc. are used as materials for manufacturing furniture, it is possible to form simply by a molding frame, so that simple curved molding is possible. Do. However, since wooden furniture is generally produced by processing flat plate materials, when a curved design is adopted to a part of the furniture, flat wood, which has been cut to a predetermined size in advance, is bent into a curved surface by a press machine or the like. However, for example, in a headboard of a bed, the surface of the headboard is unevenly decorated in order to chamfer the edge portion in a curved shape by cross-sectioning the peripheral edge portion or to improve the design of the headboard. There is a case. Such cross-sectional processing and the decorative shape of the surface of the headboard are processed by a cutting machine, and the headboard having the cross-sectional processing and the decorative shape of the headboard surface is finally painted and finished. However, as described above, for example, when the entire headboard is designed into a curved surface, as described above, after the wood of the plate is bent into curved surfaces, the cross-sectional processing of the peripheral edges, the decorative processing or the painting of the surface is performed. In order to perform this, it is necessary to control the cutting machine or the nozzle for painting three-dimensionally so as to follow the curvature of the plate. In particular, since the cross-sectional machining of the periphery of the plate is controlled to follow the outer shape of the headboard and the curvature of the plate, if this is automated with a cutting machine, it is necessary to perform very complicated control. When automated with a cutting machine, it cannot be done without the use of an expensive five-axis control machine. For this reason, in the case of employing a curved surface design in wooden furniture such as a headboard, most of the time, only the curved boards are curved, and most of them have not been processed such as cross-sectional processing. That is, in the case of wood-based materials in general, there is a variation in the moisture content of the material itself, a variation in the storage state of the material (the state of the warehouse), and a constant value is maintained even at the temperature and humidity at the time of processing. Since it is difficult to make, the bending angle is hard to be kept constant. In addition, since backlash occurs, processing after bending is very difficult in manufacturing. If it is a simple arc shape, it can be processed, but it is very difficult to be sophisticated and high precision.

The present invention has been made with this in mind, and its object is to provide a variety of finishes to be applied to a cosmetic material formed into a curved surface without the need for an expensive five-axis control machine, so that more The present invention provides a surface forming method of a curved decorative board that can increase the degree of freedom of design.

It is housed in home.

In this way, when covering the decorative board formed in a curved shape with a cloth, two pieces of cloth are sewn together to form a bag, and the decorative board is covered by covering the decorative board. At this time, a seam allowance is formed on the back side of the fabric sewn into a bag. Since this seam allowance is accommodated in the recessed groove formed by the step groove of each board | substrate, a clean appearance is obtained without wrinkles etc. in the surface side of a cloth. Moreover, since the recessed groove which accommodates the seam allowance of this cloth is formed in the state where each board | substrate is flat, what is necessary is to control so that it may follow the periphery of the board | substrate or cosmetic material, and it is necessary to perform three-dimensional control which follows the curved surface of a board | substrate or cosmetic material. There is no production processability.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described, referring drawings. 1 to 5 show the headboard A of the bed as a cremation board according to the first embodiment of the present invention. This headboard A is comprised from the board | substrate 1 and the cosmetics 2 which were adhere | attached and integrated with the adhesive agent on the surface. The substrate 1 and the cosmetic material 2 are made of wood board materials such as plywood, particle board, MDF (heavy fiber board), and the substrate 1 and the cosmetic material 2 are formed by cutting the flat wood board material. have. Moreover, the chamfer 3 is formed by the cross-sectional process of the peripheral part of the board | substrate 1, and the edge part of the board | substrate 1 is rounded. On the other hand, also about the cosmetic material 2, the tapered chamfer 4 is formed in the peripheral part by a cross-sectional process. And the cosmetic material 2 forms the coating layer 5 on the surface by the synthetic resin material which mixed the pigment, a coloring agent, abrasion resistant material, a diluent, etc. with acrylic resin, urethane resin, etc., and prepared it. Moreover, the board | substrate 1 forms the coating layer 6 by top clear, such as an acryl type and urethane type.

In this way, the board | substrate 1 and the makeup material 2 which cut and form the board | plate-shaped wood board material are formed, and the chamfers 3 and 4 are formed by cross-sectional processing, and the board | substrate 1 and the makeup material 2 of After the coating layers 5 and 6 are formed and finished on the surface, they are joined by an adhesive. Moreover, when the board | substrate 1 and the cosmetic material 2 are bonded together, in order to position the board | substrate 1 and the cosmetic material 2 mutually, the board | substrate 1 as a positioning means is called a plurality of what is called a dowel pin. The engaging convex portion 10 is assembled, and the engaging convex portion 10 is engaged with the engaging concave portion 11 formed on the cosmetic material 2 to position the substrate 1 and the cosmetic material 2 together. . And the board | substrate 1 and the makeup material 2 which were joined in this way are pinched by the pair of frames 7, such as a press, and the like, and the headboard A curved in the up-down direction is formed. In addition, although the cosmetic material 2 and the board | substrate 1 are cut | judged in the same size, after joining and bending both, the outer periphery edge of the cosmetic material 2 joined to the surface side of the board | substrate 1 It is located inside the outer edge of the substrate 1.

As described above, in the present embodiment, the substrate 1 and the cosmetic material 2 are formed through the cutting process of the wood board material. Thereafter, the edges of the substrate 1 and the cosmetic material 2 are cross-sectional processed to form chamfers 3, 4 at the peripheral edges of the substrate 1 and the cosmetic material 2, and the substrate 1 ) And the surface of the cosmetic material (2). Since the cross-sectional processing and coating of these board | substrates 1 and the cosmetic material 2 are performed in the state in which the board | substrate 1 and the cosmetic material 2 are flat, at the time of the cross-sectional processing of the board | substrate 1 and the cosmetic material 2, The cutting machine for forming the chamfers 3 and 4 of the substrate 1 and the cosmetic material 2 only needs to move planarly along the edges of the substrate 1 and the cosmetic material 2. In addition, the coating of the cosmetic material 2 is also carried out in parallel with the substrate 1 and the cosmetic material 2 in the same manner as in the manufacturing process of the flat headboard to form a uniform coating layer 5, 6. can do.

14 and 15 show a third embodiment of the present invention, in which parts having the same functions as the above embodiments are denoted by the same reference numerals, and only the other parts will be described.

In each of the above embodiments, two headboards A are shown together. In the present embodiment, the headboard A is formed by laminating a plurality of thin plate-like cosmetics 30 on the substrate 1. Thus, by bonding the some cosmetic material 30 to the board | substrate 1, the headboard A excellent in three-dimensional feeling and the curved board | substrate can be formed easily.

In addition, this invention is not limited to the said Example, A various deformation | transformation is possible within the scope of the summary of this invention. For example, in the above embodiment, the headboard is described as an example of a decorative board, but the present invention is not limited to this, but is applicable to various furniture products such as a back of a sofa or a chair, an armrest or a front plate of a chest, a table, and the like. The present invention is not limited to furniture products, but can be applied to various products such as building panels such as door panels and partition plates. Moreover, what is necessary is just to select the shape of the board | substrate 1 or the cosmetic material 2 suitably, for example, forming in a circle according to the site | part to be used. Thus, when the board | substrate 1 and the cosmetic material 2 are made circular, it is good to form a chamfer 3 and 4 by carrying out the cross-sectional process in the whole periphery. In addition, the shape of the chamfers 3 and 4 formed in the board | substrate 1 and the makeup material 2 is not limited to each said Example, For example, the edge of the board | substrate 1 and the makeup material 2 is, for example. You may form in a part arbitrarily. In addition, although the board | substrate 1 of a wood board material and the metal punching metal 15 were shown as a combination of a heterogeneous material in the 2nd Example of this invention, even if cloth or leather is stuck to the surface of the board | substrate 1 of wood board material good.

The cloth B is composed of two pieces of cloth B1 sewn into a bag shape, and a thin cushioning material H is interposed on the inner surface side of the cloth B. When the two pieces of cloth B1 are sewn into a bag to cover the headboard A, a seam allowance C is formed on the back surface side of the cloth B sewn into a bag. For this reason, when the cloth B is covered by the headboard A, the part of the seam allowance C is excited, and a wrinkle worsens, a shape deteriorates. In order to eliminate this, when the step groove 31 is formed in the inner edge of each board | substrate 1 which comprises the headboard A, and when two board | substrates 1 are bonded, the surface of each board | substrate 1 overlapped. At the circumferential edge of the concave groove 32 for accommodating the seam allowance C of the cloth B by the step groove 31 of each substrate 1 is formed. Each stepped groove 31 is formed by cross-sectional processing together with the chamfer 3 when the substrates 1 are in a flat state, similarly to the above embodiments. As a result, the step groove 31 and the chamfer 3 can be processed by a general NC router or the like, and the manufacturing cost of the headboard A can be greatly reduced, and the production processability is also excellent. Then, the headboard A, which is formed by joining and integrating the two substrates 1 on which the stepped grooves 31 and the chamfers 3 are formed, is integrated by bending with a press or the like to form a curved surface. At this time, the headboard A is covered with the cloth B sewn into a bag, but at this time, the seam allowance C formed on the back surface side of the cloth B is stepped groove 31 of each substrate 1. Since it is accommodated in the concave groove 32 formed by (), the seam seam C does not generate | occur | produce the uneven | corrugated wrinkles etc., and its appearance is also good. In addition, the step groove 31 (concave groove 32) formed in each substrate 1 by the cross-sectional processing, as in the fourth embodiment of the present invention shown in Fig. 16, accommodates the seam allowance during fabric bonding. In addition, as shown in FIG. 17, it is also possible to insert the trimming decoration material 33 formed by aluminum etc. which trim the outer periphery of the headboard A. FIG.

Also, processing performed on a substrate, a cosmetic material, or the like is also performed, for example, as in the fifth embodiment of the present invention shown in FIG. 18, to form an uneven decorative portion 30 on the surface of the cosmetic material 2, or As shown in the sixth embodiment of the present invention, inclined hole portions 35 may be formed in the substrate 1 and the cosmetic material 2 in parallel. Thus, when forming the uneven | corrugated decorative part 30 and the hole part 35 by the cutting in the surface of the cosmetic material 2, the decorative part (with the board | substrate 1 and the cosmetic material 2 being a flat plate) 30 and the hole part 35 can be manufactured very simply, and after joining the board | substrate 1 and the cosmetic material 2 in which the decoration part 30 and the hole part 35 were formed in this way, a board | substrate By curving (1) and the makeup material 2, the curved headboard A on which the decorative process was performed can be easily produced. In addition, when the hole part 35 is formed in the board | substrate 1 and the cosmetic material 2, the board | substrate 1 and the cosmetic material 2 are painted in a different color, and the back side is provided through the hole part 35. The color of the board | substrate located can visually confirm, and these contrasts improve designability more. In addition to bonding, which is a means for bonding the substrate 1 and the cosmetic material 2, the bonding may be performed by fixing means such as screws.

In the above embodiment, the circumferential engaging convex portion 10 is formed on the substrate 1 constituting the headboard A as the positioning means, and the engaging concave portion 11 is provided on the cosmetic material 2. Although the substrate 1 and the cosmetic material 2 were positioned with each other by forming the coupling protrusions 10 and the coupling recesses 11, the substrate 1 and the cosmetic material 2 were shown. When the headboard A is curved to overlap each other, the curvature radius of the cosmetic material 2 located on the outside and the substrate 1 located on the inside as the plate thickness of the head board A becomes thicker. Becomes large. For this reason, when forming the headboard A in a curved shape, there exists a possibility that the board | substrate 1 and the cosmetic material 2 may shift | deviate. As the positioning means for preventing the misalignment of the substrate 1 and the cosmetic material 2 during such curved molding, as shown in Figs. 20 and 21, one end side of the substrate 1 and the cosmetic material 2 is formed in the first direction. Similarly to the embodiment, the grooves 40 are positioned by the engagement protrusions 10 and the engagement recesses 11, and long on the other side of the substrate 1 and the cosmetic material 2, which are long in the cosmetic material 2. ), And the projections 41 that slide along the long grooves 40 are fixed to the substrate 1.
